Operation Definition

Completely taking over a physiological function by extracorporeal means

Procedure Overview

Performance procedures in this family cover situations where a machine completely takes over a vital body function because the organ responsible for it can no longer do the job on its own, even temporarily. The clearest example is mechanical ventilation, where a ventilator fully manages breathing for a patient whose lungs or respiratory drive have failed. Cardiac output support that fully substitutes for heart function during a cardiac arrest or profound shock state falls into this same category, as does extracorporeal circulation used during certain surgical or resuscitative situations.

These interventions are used in intensive care and operating room settings for patients in acute respiratory failure, cardiac arrest, or severe hemodynamic collapse. The goal is to keep a patient alive while the underlying problem, whether pneumonia, a drug overdose, a heart attack, or post-surgical shock, is treated or resolves on its own. Duration can range from a single episode during a code event to days or weeks of continuous ventilator support.

Because the device is doing the entire job of the organ rather than helping it along, this is a more intensive level of intervention than support or assistance, and documentation typically reflects a patient who is critically ill or medically unstable.

Anatomy & Axis Detail

Biliary

Biliary performance refers to a device fully taking over a function normally carried out by the biliary system, most typically external drainage of bile when the normal pathway from liver to duodenum is obstructed or disrupted, such as by a tumor, stricture, or postsurgical complication. Because bile has nowhere else to go once its natural drainage route is blocked, a percutaneous or endoscopic drain effectively performs the system's job of removing bile from the body until the underlying obstruction is corrected. This is typically a temporary measure bridging toward more definitive treatment like stenting or surgical repair, so documentation of the expected or actual duration is clinically meaningful. The biliary system's connection to digestion and liver function means prolonged external diversion can have nutritional and metabolic consequences that shape how long this performance is continued.

Duration: Multiple

Multiple indicates the extracorporeal assistance or performance procedure was performed as more than one distinct session or treatment during the episode of care, rather than a single isolated event. It is paired with Single as a simple either-or distinction reflecting how many times that particular function was carried out.

Function: Filtration

Filtration describes extracorporeal removal of substances from the blood, such as in hemofiltration or similar renal replacement support. It is distinguished from Cerebral Embolic Filtration, a narrower value for devices capturing embolic debris during cardiac procedures, by referring to systemic blood filtration for waste or fluid removal rather than a protective, procedure-specific application.

Coding & Documentation

A code from this family requires documentation showing the body function was entirely replaced, not merely boosted. For ventilation, this generally means invasive or noninvasive mechanical ventilation is stated explicitly, along with the duration, since ICD-10-PCS values differ for less than 24 hours, 24-96 hours, and greater than 96 hours. For cardiac output, the record should describe a device or circuit taking over pumping function completely, as with extracorporeal membrane oxygenation used for cardiac support.

The most common assignment error is coding Performance when the physician documentation actually describes partial or intermittent support, which belongs under a different root operation. Coders also frequently miscount ventilator duration, especially when a patient is intubated, extubated, and reintubated within the same stay; each qualifying episode needs separate attention rather than simply summing hours loosely. Another recurring mistake is failing to update the duration value when a ventilator course extends past a threshold, since the code should reflect the total qualifying time, not just the initial order.

Commonly Confused With

AssistanceThis family is frequently confused with Assistance procedures in the same section, which cover a device that helps a physiological function without completely replacing it, such as an intra-aortic balloon pump augmenting cardiac output rather than substituting for it.
RestorationIt is also confused with Restoration, which describes returning a function toward its original state, such as cardioversion, rather than taking over the function outright.
